Büroklammerbild speichert nirgendwo (missing.png) Schienen

Question

Ich benutze Büroklammer Edelstein, um Bilder hochzuladen, aber diese Bilder werden nicht im Öffentlichen Ordner oder sonstwo gespeichert, stattdessen zeigt es missing.png. Ich habe bereits URL, Pfad angegeben.

Modell - Dies ist das Modell mit Büroklammer konfiguriert

class AudiModel < ActiveRecord::Base 

    has_attached_file :exterior_image, 

    :path => ":rails_root/public/system/:attachment/:id/:style/:filename", 

    :url => "/system/:attachment/:id/:style/:filename", 

    :styles => { :medium => "300x300>", :thumb => "100x100>" } 

    validates_attachment_content_type :exterior_image, content_type: /\Aimage\/.*\Z/ 

end

    before_action :set_audi_model, only: [:show, :edit, :update, :destroy]

es gelöst! Pfad sollte wie sein. Sie müssen den Attributnamen auch im Pfad angeben.

: path => ": RAILS_ROOT/public/system/exterior_image /: attachment /: id_partition /: style /: Dateiname"
